RCA CC174 Digital Camera Replacement Battery 6V 4200mAh

RCA CC174 / CC177 / CC178 / CC180 Series — 6V Ni-MH 4200mAh Replacement Battery

This is a 6V Ni-MH battery rated at 4200mAh (25.2Wh) for the RCA CC174 and related camcorder models. It replaces the original pack in the CC174, CC177, CC178, and CC180, plus 22 additional compatible models in the same series. Drop it into the battery compartment and charge before your first shoot.

• CC174 / CC177 / CC178 / CC180 series compatibility: These models share the same 6V battery bay, connector pinout, and BMS communication protocol — which is why a single pack covers the entire run. Voltage rail and physical form factor are identical across the group.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the CC174 body. The BMS accepted the cell without error flags, and the charge circuit completed normally through the camera's onboard charger interface.
• First-cycle initialisation on Ni-MH cells: On first install, run a complete charge cycle through the OEM charger or camera body before shooting. Some RCA camcorder BMS units need one full charge-from-empty pass to correctly map the remaining-power display to the new cell's discharge curve.

Dead battery indicator on a partially charged replacement cell

RCA camcorders in this series use a voltage-threshold map to estimate remaining charge — a map calibrated to the original cell's discharge curve. A new Ni-MH cell can sit at a voltage that the camera reads as critically low, even when the cell holds a strong charge. This usually clears after one full charge cycle completed inside the camera body, which lets the BMS reset its reference points. If the indicator still misreads after that, check the charger output is reaching the full 6V endpoint before removing the battery.

Battery percentage jumping erratically during recording

Ni-MH cells have a flatter mid-discharge voltage curve than Li-ion, which means the camera's percentage display can jump in uneven steps — especially in the upper and lower 20% of capacity. This is a display mapping issue, not a fault with the cell. The battery itself is delivering stable current while the indicator struggles to resolve where it sits on the curve. Charge the battery to full and let it discharge through one complete session to allow the BMS to re-anchor its threshold points to the new cell.
